I was going to list How do they annoy me? Let me count the ways. (Shakespeare?)
It is sad that good manners or even mild consideration is no longer thought of as needed. People are maybe educated by the insanity in the media? We used to dress nicely for church, plane flights, going to 'the city'. We used to say excuse me and thank you. And over the last couple of decades that all decayed. But lately, here, things seem to be getting better, not worse.
Playing the devil's advocate, Things still bother me, but when I think about it, it is maybe me. The person in a hurry behind me is not doing it to annoy me. People/kids having fun with gay abandon are not even thinking about annoying me. I should learn to revel with them in my head, not growl there.
But then I will lose my curmudgeon standing.
